The wheel of many broken spokes
A few years ago, I bought a cheap wheel at my local shop for my fixed gear bike. I didn't have a track hub handy, so it was cheaper and faster to just buy a wheel instead of build one up. It has 36 straight gauge spokes, so I thought it'd be plenty durable.
In point of fact, it has not been durable. I break spokes a lot. In the past week, I've broken two spokes (once while riding rollers). I've had as many as three break on a long ride before. Since there are 36 spokes, 1-3 missing isn't a big deal and I make it home with a wobbly wheel.
Whenever a spoke breaks, I replace it with a nice double butted, high quality spoke from DT or Sapim. Out of the 36 original spokes, I think I'm down to about 12 or so originals. I figure by the end of this winter, I'll have them all changed out, and I'll finally have a reliable wheel.
I could change all the remaining spokes at once, but where's the fun in that?
i figure with a big guy like you on a fixie you should be going with tied and soldered straight gauge high tension spokes...
